Vintage Synth Repair

Hi Ethan,

You will probably find that the 'noise' (if you mean actual sound rather
than instability of supply), is caused by the
transformer. Check the transformer mountings for security and tighten down
where required. This may help.

Regards,

Ron.

  Subject: [vintagesynthrepair] Repairing power supply.


  I have an old +/-15v .5A power supply that is very noisy and I
  suspect it is in need of servicing; potentially a rebuild.  Does and
  body have experience doing this kind of thing?  I have schematics and
  a service manual and my scope should be here monday.

  Any help will be greatly appreciated.

  Thank in advance,

  Ethan
